Hayward FLEX TUBE NEST -EC40AC-

The Hayward Flex Tube Nest for the EC40AC model is the core internal filtration assembly engineered for the Perflex extended-cycle D.E. filter system. This assembly consists of a series of specialized flexible tubes, known as "fingers," which are securely seated between a top and bottom tube sheet. Its primary mechanical function is to provide an expansive surface area for Diatomaceous Earth to coat, enabling the system to capture microscopic impurities and debris from the pool water. The unique "flex" design allows the tubes to move and shift when the external bump handle is operated, a process that dislodges the spent D.E. cake and redistributes fresh powder without requiring a traditional backwash. Constructed from high-strength, chemical-resistant thermoplastics and synthetic fabrics, the nest is built to maintain its structural integrity under high hydraulic pressure and constant mechanical movement. For shipping and logistical purposes, the estimated weight of the Hayward Flex Tube Nest for the EC40AC is approximately 10.5 pounds in its retail protective packaging, while the actual dry weight of the tube nest assembly itself is roughly 8.2 pounds.
